Description of the Related Art Conventionally, in a reel-type lawn mower, a twisted rotary blade plate is attached at an angle close to a rotation axis of the reel so that the lawn is scissors between the blade and a straight blade-shaped receiving blade. It's cutting. It is generally said that the gap between the two blades needs to be accurate enough to cut a single newspaper. Therefore, even if the size is small, if the solid material is bitten and the size of the gap is changed, the grass cannot be cut. In addition, it is difficult for an amateur to finish polishing the blade with minute breakage or abrasion, and it is troublesome for repair and maintenance, and there is a problem in sharpness durability. Further, the reel-type lawnmower has a function of only mowing with a certain size including other weeds.

ール軸のシャフトカバーも必要である。According to the present invention, basically, a back blade is provided between a large number of projections provided on at least one of a rotary blade and a support receiving blade, and an object sandwiched between the projections is provided. It has a structure that impacts the turfgrass against the other blade to provide an impact cutting action. That is, the rotary blade is attached at a position along the outer peripheral surface of the reel to reduce the resistance to high-speed rotation, and the blade is detachably attached to the reel to facilitate repair and polishing. A deep blade is provided between a number of protrusions to prevent damage to the deep blade due to solid matter and to maintain sharpness for a long time. For lawn mowing, the shape of the protrusion is most preferably tapered and has a blunt tip and sharp side blades to make it continuous with the back blade, and to selectively mow only weeds without mowing grass in the lawn. Has a blunt blade with a uniform width, and the tip is formed upward with a sharp back blade to enable shallow ground leveling in grass with a small amount of pebbles. The receiving blade of the present invention supports an object from the rear side and is therefore called a supporting receiving blade. When the supporting blade is a straight blade, an inner blade is provided between a large number of protrusions provided on the rotary blade, and the target turfgrass is sandwiched between the protrusions to cause the blade to crash into the supporting blade. When the rotary blade is a straight blade, a large number of tips provided on the front edge of the support receiving blade form a deep blade between the robust projections. In the dense grass, the grass entangled with the projections is loosened to stand up, or the solid material is repelled by the tip to keep the sharpness of the back blade long. The target turf is sandwiched between the protrusions and pushed from behind to support it, and the flexibility of the turf is killed, and the rotary blade is effectively slammed to the front slightly upper part to shockly cut the turfgrass of the target. Further, the support receiving blade is configured to elastically lower when it collides with a solid material. With this configuration, for example, the impact when the solid matter is bitten is reduced, and the wear of the device, the support receiving blade, or the rotary blade is prevented. It is not a rotating type support blade and it is connected to an external rotating tool, and the rotation operation allows the support blade to mow the lawn in the lower position and retain the mowing function in one device in the upper position. Excuse me. Further, the reel is configured to be capable of both forward and reverse rotation. Then, a weeding tool and a dividing wall of the exhaust air flow path are provided at the rear of the reel inside the device and are divided into upper and lower parts. When cutting grass, the grass is discharged from the upper exhaust air flow path so that one device has two functions. By reversing, we can provide a device that can even mow the grass and even the ground. Furthermore, the support receiving blade of the above-mentioned forward / reverse rotation type device is configured to be rotatable, and is operated upward or downward from the outside of the device,
A single device can hold three functions by combining the shapes of the blades of the rotary blade, such as lawn mowing by forward rotation and mowing in the lawn, and weeding that also functions as ground leveling by reverse rotation. A shaft cover for the reel shaft is also necessary to facilitate the above work.

に望ましい。Embodiment I (FIGS. 1 to 13) The drawings show an embodiment I of the reel type lawnmower according to the present invention.
The lawn mower 1 is driven by the motor 25 through the motor pulley in the pulley cover 30 and the reel pulley, and the reel shaft 19
Is rotated in the direction of the arrow and the handle 3 is pushed to
Work in the direction of the arrow inside. The handle 3 is detachable from the mounting boss 4 and has a switch 27 at hand.
The left and right side walls 31, 32 of the lawn mower are formed by press working to form rising edges along a peripheral edge of a flat metal plate, and a grass collecting tool 2 is detachably attached to the front upper part of the machine body 1. There is. The support structure of the support blade is such that the adjustment knob 12 and the adjustment rod 14 at the lower rear part of the machine are integrally attached to the support blade 1.
It is rotatable so that it can be tightened downward by the upper adjustment plate 15 through the upper left and right suspension springs 37 and the lower adjustment spring 13 through the suspension holes 36 on the left and right of the rear part of 0. Further, adjustment shaft holes 11 are provided in the upper left and right sides of the center of the support receiving blade 10 (FIG. 3), and the left and right side walls 31, 3 are rotatably supported by the adjustment shaft 16.
It is attached to 2. Therefore, when the support receiving blade 10 is displaced, is worn, or is extremely open from the rotary blade 17, it is possible to adjust to a desired gap with the adjusting knob. In the reel, a plurality of cross-shaped metallic reel plates 18 are fixed to a reel shaft 19, and one rotary blade body 17 is attached to each of the outer peripheral ends of the four support pieces. It is attached to. A rear wheel 9 is rotatably fitted to a rear wheel shaft supported by left and right side walls 31 and 32 at a lower rear portion of the reel. 4, 5 and 6, a front wheel 8 is fitted on the front lower wheel shaft 24 at the lower front portion so as to be rotatable left and right. The left and right ends of the front wheel shaft 24 are fixed to the support holes 23 near the center of the left and right height adjusters 7 (FIGS. 3 and 6), and the rear end of the height adjuster 7 has a height. It is rotatably attached to the front portion of about one-third below the left and right side walls 31 and 32 by an adjusting shaft 20, and the front portion is bent in a U shape and loosely fits in an adjusting hole 34 provided on the front side. The height adjusting knob 6 is screwed into and fixed to the screw thread at the front end of the adjusting rod 14. Further, a square brim 22 is fixed to the central side of the adjusting rod 14, and a height adjusting spring 23 is loosely fitted to the front surface of the brim 22 to secure the inner surface of the wall of the front height adjusting tool. Pressure contact. Further, the height adjusting rod 1
The rear end of 4 fits loosely into the central hole of the stopper 21,
The front side of the stopper 21 is pushed by the adjusting spring pressure via 2. Therefore, the height adjustment knob 6 in the direction of the arrow shown in FIG.
When pulling, the rear end of the height adjusting rod 14 comes off from the height adjusting hole provided on the rising edge of the front part of the side wall shown in FIG. 2, so while pulling the height adjusting knob, any height adjusting hole 5 Can be moved to the position, and while the knob is returned, the knob is fitted into the target height adjusting hole, and the height at a predetermined position, for example, L 1 , L 2 , L
You can keep the front wheel at 3 . The support receiving blade 10 has a rear blade formed between a large number of triangular protrusions, and has an arc surface in the front-rear direction, the top surface of which is approximately the same as the arc of the rotating surface of the rotating blade. Although it is shaped and the front edge of the protrusion is formed in a warp, this is because even if the gap is eliminated, it does not mesh with the front edge of the rotary blade. Further, the left and right longitudinal directions are bent downward by about 15 degrees at the boundary between the support portion of the blade body and the front blade portion, and the adjustment shaft holes 11 are provided in the ears provided on the left and right sides of the support portion. It is rotatably attached to the left and right side walls 31, 32 by an adjusting shaft 16. Further, the adjusting plate 15 is attached to the uppermost end of the adjusting rod 14 which penetrates the hanging hole 36 at the rear of the ear provided with the adjusting shaft hole 11 and suspends the supporting blade (FIGS. 7 and 8). 9). Therefore, when the adjusting knob 12 is turned to lower the adjusting rod downward, the support receiving blade 10 also rotates upward about the adjusting shaft 16 so that the gap between the supporting blade 10 and the rotating blade can be made small, and the solid blade between the supporting blade 10 and the rotating blade can be reduced. When the object is bitten, the upper adjusting spring contracts and the supporting blade moves in the direction of arrow P, so that the impact is mitigated.
Further, the blade edge is prevented from moving upward by the elasticity of the lower adjusting spring 13. The tips of the supporting blades loosen or erect the foliage of the target turf, and protect the sharpness of the back blade from large solid matter to improve durability. The rotary blade is
In FIGS. 10 and 11, a rotary blade 17 having a straight blade is formed.
Is formed such that the bottom surface has both the front and rear edges with the blade outer surface facing inward from the tangent line of the rotation circumference R and an angle such as a straight line LL ′.
The angle is such that the blade edge does not bite the supporting blade even if the gap with the supporting blade is slightly filled. Also, since the reel holes can be screwed to the edge portions of the reel plate by the mounting holes, the rotary blade body can be converted back and forth even at the work site, and polishing is also easy. Further, as an example of a shape that easily protects the blade from solid matter, in FIGS. 12 and 13, the rotary blade body is provided with a back blade between a large number of projections, and the front end of the projection is close to the axis and solid. When hitting an object, it is easy to avoid it, and has the effect of protecting the back blade from a large solid matter. The deep blade is not limited to this example, and it is desirable to have a shallow edge such as an arc shape. As described above, the cutting height of the reel type lawnmower according to the present invention can be adjusted. The large number of protrusions on the supporting blade protect the back blade from large solid objects, loosen the entanglement of long grass, make it upright, and make it easier to clip the grass.
In addition, the support blade is a sharp back blade that cuts the target turf and pushes it forward slightly below the height, which reduces the flexibility of the turf.
Since the rotary blade from the front collides with each other and the lawn pressed by the impact of the rotary blade is also cut by the support receiving blade, the target lawn is easily cut at a relatively low speed.
Therefore, even if the solid matter is caught between the rotary blade and the support receiving blade and the mutual gap is slightly widened, the cutting force is not cut but is cut by the impact force of the rotary blade, so that the cutting force hardly changes. The firmness of the lawn varies depending on the season, humidity, and variety, but in order to minimize discoloration after cutting, the speed of the rotary blade is adjusted by the motor controller 29 to reduce the lawn to the lowest speed at which it can be cut. It is possible and desirable to clean the finish.

Since the arrangement and functions of the grass collecting tool 52 and the like are almost the same as those in the first embodiment, the description thereof will be omitted here, and the supporting blades different from the preceding example will be described in detail. That is, the supporting blade of this example has no adjusting rod, adjusting spring, etc., and is configured to be rotatable, and the supporting pins fixed to the rotating support portions 40 provided at the left and right ends on the rear side are provided with supporting holes in the side wall. It is fixed to one end of an elastic flat plate support 48 through the outside. Further, a knob 51 for operating the support tool and a fixing hole are provided at the other end of the support tool 48. In addition, the lawn mowing fixing projection 50 which is fitted into the fixing hole to stabilize the supporting tool.
A grass cutting fixing projection 49 is provided at a predetermined position on the outside of the side wall. Furthermore, when the support blade 10 is in the position of lawn mowing,
A receiving member 46 that closely supports the lower surface is fixed at the inner surfaces of the left and right side walls at both ends, and the front edge portion of the receiving member has an appropriate gap with the rotary blade. This gap is configured to have a width such that a large mowed grass can fly smoothly through the gap. Therefore, in FIG. 18, the knob 51 is pulled away from the wall to disengage the fixing hole from the lawn mowing fixing projection 50, and is rotated as shown by the arc-shaped broken line arrow to move the grass cutting fixing projection 4.
When the support tool 48 is fixed at the position indicated by the broken line by fitting the support receiving blade 10 inside the body 9, the support blade 10 inside the body rotates as indicated by the thin arc-shaped arrow in FIG. 17 and is fixed to the front side of the guide wall 26 as shown in FIG. It In this case, the grass is being mowed, and the mowing grass is the rotating wind force of the reel. As shown by the small arrow, the space between the guide wall 26 and the rotary blade is located above the support receiving blade and the rotary blade below. It is skipped and enters the grass collecting tool 52 attached to the upper front.
By reversing the above operation and returning the guide tool 48 to the position shown in FIG. 18 and fitting and fixing the fixing holes in the lawn mowing fixing projections, the rotatable support receiving blade 10 overlaps the receiving tool 46, and it becomes The shock is supported by the receiver. In this lawn mowing state, the impact-cut grass lawn is skipped between the guide wall and the rotary blade as shown by the thick arrow in FIG. 17 to enter the grass collecting tool. If the above-mentioned receiving member is elastically configured or attached via a spring, the impact received by the rotary support receiving blade can be alleviated. Furthermore, by forming a large number of shallow protrusions on the front edge of the receiving device, there is an effect of sweeping the cut grass when cutting the grass in the lawn. As described above, in this embodiment, two operations, that is, lawn mowing and lawn mowing can be performed separately by operating the rotary support blade. Although not shown in the figure, the motor controller performs the same function at the same position as in Example 1, and additionally controls the motor speed according to the hardness of the grass depending on the season, humidity, etc. The rotation speed of the reel can be determined. Although the electric motor has been described above as an example, the same operation and effect can be obtained by implementing a similar function even if another prime mover, for example, an internal combustion engine is mounted.

好ましい。Third Embodiment (See FIGS. 24 to 29) This embodiment is a reel-type lawn mower / mower 2 using both forward and reverse rotation, and the shape of its rotary blade is shown in FIGS.
The multiple tapered projections 38 formed on the front edge of the rotary blade 17 become thinner toward the front end, the sharpest end is blunt and has a slight width, and sharp edges are formed on both sides of the projection as well. Although the back blade is also downward as shown in (4), it has a shape that is more resistant to collision with solid matter and has a higher lawn cutting force than the straight blade. Further, the equal-width projections 39 provided on the rear edge portion have the same width from the root to the most apex, and the back blade is upward, so that the strength against solid matter is greater, and the back blade between the projections is upward, The strength is large so that weeds can be rooted, cut and leveled at the same time when mowing the grass. Therefore, in the forward rotation, the leading edge with a large lawn mowing force is used, and in the reverse rotation, lawn mowing is not possible unless the number of rotations is extremely increased.However, use the trailing edge that can control the number of rotations and mow the lawn. become.
The figure shows that the blade has a flat plate shape, but it is more preferable if it is a curved plate close to the outer peripheral surface of rotation of the reel, and about 10 degrees in the longitudinal direction in the middle of the blade body, for example, press working. It is also preferable to bend at. A grass collecting tool 52 is detachably attached to the opening of the body of the machine, and the operator pushes the handle 3 from the rear to work forward. Although the height of the machine is adjusted by the rear wheels, the construction thereof is the same as that of the first embodiment, and therefore the explanation thereof will be omitted. The difference from the supporting edge adjusting device of the first embodiment is that the adjusting shaft 16 is the same as the height adjusting shaft (FIG. 27). Secondly, a buffer spring 37 is interposed below the adjusting shelf 35 to widen the interval between the adjusting plate 36 below and the adjusting shelf 35. Therefore, when the solid matter is sandwiched between the support receiving blade 10 and the rotary blade 17, the adjustment shelf 35 rotates about the adjustment shaft 16 and is elastically lowered in the direction of the arrow P. Since the space between the line R and the line R spreads out, the impact of sandwiching the solid matter is mitigated (FIG. 28). A motor 25 and a motor controller 29 are mounted and connected above the front part of the machine body, and the number of rotations of the motor can be continuously controlled from 0 to 100%. Further, when the above reel shaft is rotated by weeding, a phenomenon in which a tough and long leaf stem winds around the reel shaft inside the bearing from the gap between the rotary blade end and the side wall rarely occurs, but as a means for preventing it, The shaft cover is attached. That is, as shown in FIGS. 26, 27 and 29, the central reel shaft 1
9. A bearing 55 fits around the outer periphery of the bearing 55. The bearing 55 is attached to the inner surface of the side wall with a bearing cover 54. Further, the outer periphery of the bearing cover is covered with the inner wall of the cylindrical shaft cover 53 to be fixed integrally with the bearing cover. is there. Therefore, since the outer circumference of the reel shaft is covered from both ends of the rotary blade to a position slightly closer to the center, a long leaf stem does not wind around the reel shaft, so that long-term work can be smoothly performed. After the motor is driven and the reel rotates in the direction of arrow A during normal rotation, the target turf is impact-cut by the supporting blade and the rotary blade, and then the weeding tool 43 from the lower rear of the reel as indicated by the small arrow. Then, it is guided to the rear discharge port by the flow-dividing grass plate 44 and jumps into the grass collecting tool. Also, since the reel is rotating in the direction of arrow B during reverse rotation,
The mowed grass is guided by a guide front plate 42 which is a lower wall surface of the rear of the motor chamber, and the grass weeding tool 43 at the rear side and the grass weeding tool 4 are provided.
By the flow dividing grass plate 44 fixed to 3, the air gap above the rear part is jumped in the direction of the small arrow, and is discharged to the rear of the machine body.
Enter (FIGS. 23 and 26). As described above, in the lawn mowing / mowing machine using both forward and reverse rotations of this example, the lawn mowing is performed in the forward direction of the arrow A, and in the direction of the arrow B, the motor rotation speed is controlled according to the situation of the site to mow the lawn. Is possible. Weeding tool 43
The left and right ends are slidably moved up and down in the weeding support tool 56 fixed to the inner surfaces of the left and right side walls, and elastically pressed downward by a cushion tightening screw 58 through a rubber cushion 57 from above. Yes, the impact when a solid material such as wood chips is caught is small, and the grass entwined with the rotary blade is removed to facilitate the work. In this example, the support blade has a cushioning structure using a cushioning spring, which improves the durability of the rotary blade and is also preferable for the durability of the mounted prime mover, for example, an internal combustion engine.

成できるのは明白である。[Embodiment 4] In this embodiment, the support receiver of Embodiment 3 is configured to be rotatable, and the lawn mowing and the grass mowing are performed in the normal rotation by the operation of the external rotating tool, and the grass mowing in the lawn is also performed in the reverse rotation. Can be implemented as shown in FIG.
7 to FIG. 23 and FIG. 27, the structure of the rotary type support blade can be easily added to the lawn mowing / mowing machine 2 according to the third embodiment by forward and reverse rotation. The rotary blade of the rotary forward / reverse double-rotating lawn mower / mowing machine of this example is preferably that shown in FIGS. 14, 15 and 16. In the forward rotation of the reel, if the support receiving blade is located below, You can mow the grass of the rice family by performing shocking lawn mowing at the front edge of the and if it is above it, you can mow a little grass with the rotation speed of the reel. Further, when the reel is reversed, the weeding tool 43 is fixed to the diversion and weeding plate 44, and the rear edge of the rotary blade is a constant-width projection and the back blade is upward, so that the grass can be selectively selected without any problem even in the lawn. Weeds softer than the lawn are mowed and discharged from above to the rear as shown by the arrow. Others are as described in detail in the above-mentioned example, but it is clear that the present example can be easily configured to be a self-propelled type or a towed type.

機能を一台の装置に具有させる効果が生じる。According to the present invention, a prime mover, such as an electric motor and an internal combustion engine, is mounted to drive and rotate a reel, and a rotary blade attached to the outer periphery of the reel has a sharp cutting edge that supports a blade slightly below the cutting height. The target lawn, which has been pressed by the back blade and has lost its flexibility, is impacted, and the lawn mowing is performed at a relatively lower speed than the rotary lawnmower. Therefore, the cutting part is less likely to be exposed to heat and discolors less, and after cutting it is more beautiful than a rotary lawnmower. Also, unlike conventional reel type lawnmowers, rather than clipping, the flexibility of the lawn is killed and impact cutting is performed as described above, so the precision of the gap between the rotary blade and the receiving blade can reduce flexibility. It can be adjusted with a small gap, and the gap is wide and easy to adjust.The blade plate of the rotary blade is not only flat, but also arc-shaped in the front-rear direction, or a half-folded plate that is slightly bent in the longitudinal direction. The selection range of
Easy to polish and repair. Furthermore, of the target grass that was hit by the rotary blade from the front, the grass that was left uncut was pushed by the sharp back blade of the supporting blade from behind, so it is easy to be cut into the back blade by the impact from the front. Will be mowed. A large number of projections provided on the rotary blade protect the sharpness of the back blade when it collides with a large solid object, so durability of sharpness is increased. In the case where the side blades are formed on both sides of the tapered protrusion, the back blade is less likely to be damaged by the collision of solid matter and the sharpness lasts longer than that of the straight blade. The monospaced protrusion does not easily deform and strongly protects the back blade, so even if a small amount of pebbles are mixed, mowing can be done in the lawn without hindrance, and grass rooting and ground leveling in the shallow layer can be performed. When the grass cutter is placed close to the rotary blade and attached to the side wall, the grass grass entwined with the blade can be removed, so the weeding work can be carried out smoothly. If the shaft cover is attached to the reel shaft, weeding of the shaft can be prevented, and the weeding work can be carried out smoothly. In the support receiving blade, the back blade is formed between many protrusions, protecting the sharp back blade from solid matter,
Since the cutting is done by impact while the inner blade is sharp, the cutting force does not deteriorate even if the gap is slightly widened. In the rotating type of the support receiving blade, the two functions of lawn mowing and lawn mowing can be performed only by forward rotation by operating the rotating tool. When mowing in the lawn when the support receiver is at the top, the projection of the receiver has the effect of sweeping the grass. With the buffer structure of the support blade, when a solid material is caught between the rotary blade and the support bracket, the buffer spring contracts and lowers the support blade downwards to widen the gap, preventing damage to the support blade and rotary blade. Prevents and enhances the durability of the aircraft. The protrusion of the supporting blade has the effect of slicing the foliage of the target turf at the tip and loosening or erecting it so that the turf is aligned and cut into equal lengths. And, in addition to the rotation type support blade, the forward and reverse rotation type lawn mower combined
The effect of having the function in one device occurs.
